' Renewed September-28, 1935 2 Claims.

The primary object of the invention is the pro- 5 vision of a machine of this character wherein, through the instrumentality of variably driven connections with a source of power, different kinds of appliances can be actuated, as for example, a churn, juice extractor, beater, mixer, grinder and numerous other implements, thus affording ahandy machine for kitchen, household or other needs. Another object of the invention is the provision of a machine of this character, wherein the same is readily portable and can be converted for a variety of uses and for power transmission at varying speeds.

A further object of the invention is the provision of a machine of this character, wherein the driving mechanism is of-novel construction and mounted in a novel manner to allow for the use of appliances of variable or different kinds and thus affordsa labor saver in the operation of such appliances.

: A still further object of the invention is the provision of a machine of this character which is comparatively simple in its construction, thOIr oughly reliable-and eflicient in its operation, enabling the convenient and easy attachment of difao ferent appliances for the use thereof, and inexpensive to manufacture.

With these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will 35 be hereinafter more fully described in detail, il-

lustrated in the accompanying drawings, which disclose the preferred embodiment of the inven-' tion, and pointed out in the'claims hereunto appended. i

Figure 11 is a fragmentary sectional view showing in detail the connection between the meat grinder and the drive mechanism of the machine,

Figure 12 is a detail sectional view showing the connection between the tool grinder and the drive ,15 of the machine.

Similar reference characters indicate corresponding parts throughout the several views in the drawings.

Referring to the drawings in detail, the machine comprises a base ID, in this instance, of circular contour, yet, it may be of any other desirable shape and is provided at its underside with suitable feet ll so that the base will be slightly elevated from a floor or foundation or other support carrying the same. Carried by the base near the marginal edge thereofis a vertical socket I I2 for accommodating an upright or post i3 which may be of any desirable height according to the requirements of use of the machine, and this post, at its upper end, is formed with a horizontally directed fork or yoke M for accommodating and supporting a swingingly mounted gear casing or housing I5 joined with an electric motor it, either for direct current or alternating current, and the same being adapted for separable connection with any suitable source of current supply. The motor It has the trunnions I1 journaled in the arms of the yoke or fork I, so that the casing or housing may be swung in a vertical direction and is limited in its swinging movement through the medium of stops I8 and. i9, respectively, the stops l8 being formed on the yoke or fork ll, while the stop i9 is on the motor. Arranged within the casing or housing I5 is a worm screw shaft 20 which is an extension or coupled with the driving shaft 2| of the motor and the outer end of said shaft 20 is extended through the casing or housing l5 and is provided exteriorly thereof with a coupling terminal 22 p for the attachment of an appliance to be operated at high speed.

At one side of the shaft 20 and within the easing or housing i5 is a largegear 23 meshing with said worm screw shaft, its arbor 24 being It extended through opposite sides of the casing or housing I5 and having the coupling terminals 25 and 28, respectively, which are centered with respect to the sockets 21 and 28, respectively, formed with the sides of said casing or housing, each socket being fitted with a set screw 29 for the detachable mounting of an appliance therein, while either coupling terminal 25 or 26 is adapted for connection with the driving medium of such appliance for slow speed operation thereof.

At the other side of the shaft 2|I and within the casing or housing l5 is a small gear 38 meshing with said worm screw shaft, its arbor 3| being extended through opposite sides of the casing or housing and centered at one side with respect to a socket 32 carrying a set screw 33, the opposite ends of the arbor 3| being formed with coupling terminals 34 and 35, respectively, for the connection of the driving mediums of appliances to be operated at a greater speed than the speed of the gear 23.

..Z|Z"ormed interiorly of the casing or housing l5 at the same side with respect to the gear is a bearing 36 flttedlwith a stud shaft 31 carrying a rack gear 38 engaging a rack bar 39, the latter the stud shaft 31 and this rack bar 39 is pivotally connected, at 4|, to a crank formation 42 built with the arbor 24 of the gear 23, so that the rack bar will be reciprocated and oscillated under the rotary movement of the gear 23 and thus oscillating the stud shaft 31 which, through the medium of a socketed sleeve-like coupling 43, can have attached thereto an appliance to be driven by oscillatory action, the coupling 43 being fitted with a set screw 44 for the attachment of the appliance therewith.

Adjustably carried upon the post I3 is a bracket 45 susceptible of horizontal swinging movement and at the free end of the same is a ball bearing equipped rotatable head 46 constituting a male fitting for a female coupling 41 therewith of a bowl rack 48 which, when containing the bowl having contents, is free for rotation so as to assure a thorough mixing of the contents of the bowl when a mixer appliance is operating within the bowl and driven by the machine. I

In Figure 1 of the drawings the casing or housing It has carried thereby at its top a fruit juice extractor including the bowl 43 which fits over the boss 50 about the arbor 3| and this arbor, through the coupling terminal 34, has connection with the juice extractor cone 5| working within the bowl 48 of said extractor. At the lower side of the casing orvhousing I5 is a mixer appliance 52, it being fastened in the socket 32 and havin connection with the arbor 3| to be driven thereby.

Adapted to be engaged in the socket 28 is a flexible connection 53 for driving an ice cream freezer or other appliance.

Adapted for connection with the sleeve-like coupling 43 is the driven flexible shaft 34 or the churn paddle 55, while engageable with the coupling terminal 25 is the driven part of a meat grinder 56, the same being detachably secured in the socket 21.

Engageable with the terminal 22 of the shaft 28 is a tool grinding disk or wheel 51. Thus it will be seen that the machine is susceptible-of operating many different kinds of appliances, particularly those that have to do with houshold or kitchen purposes or for farm activities, as for example, churning, and for the operation of a clothes wringer, washing machine or other contrivance.

In the use of the machine as a churn, of course, it is understood that the bracket is either removed or shifted out of the way of the churn body when placed upon the base III, the bracket being service'- able for the operation of the machine as a mixer.

In Figure 5 of the drawings there is shown a clothes wringer 58 which has its mounting 88 engaged in the socket 21, and resting upon the base I0 is a washing machine body 60, while in Figure 3 the churn body 6| restsupon said base.
